Max George‘s girlfriend is truly a multi-tasker … she can PDA and pick the thong out of her ass AT THE SAME TIME!!!!

Max — the guy from The Wanted who once banged Lindsay Lohan — took his hot model GF Nina Agdal to a beach vacation in the Bahamas … where they galavanted around with their ridiculously attractive tan bodies.

They spearfished … they yachted … they boozed — and most importantly, they documented almost the entire thing on camera so everyone could follow their half-naked vaca.
